Title: Indicator for centrifuge solids discharge - being flow passage between solids collection chamber and centre with nozzle and gauge
Inventor: STROUCKEN KLAUS HANS DIETER
IPC: B04B1/10
Filed: 1975-02-05
Abstract: Method for detecting when solids from centrifuge bowl need to be discharged consists of a channel (I) running from the solids collection chamber to the centre of the centrifuge via a chamber (IV) and channel (II). At the end of channel (II) is a restriction or nozzle which controls the liq. flow. When the centrifuge is rotated liq. leaves via channel (III) and the liq. level in the bowl up to the chamber (IV) and a probe and gauge shown a definite pressure. Some liq. flows through the nozzle down to the centre and the level stabilises. However as solids accumulate in the collection chamber, passage (I) becomes blocked and the level in the bowl recedes until the probe becomes exposed. This then causes a sharp drop in the pressure shown on the gauge. The nozzle is so designed that it does not become blocked with particles. This is achieved by giving it a conical cross section with the narrowest part at the entrance and then having a sharp increase in section following. Of use on bathc centrifuges for determining the optimum point for solids discharge.

Title: Electronic adjustment circuit for AC signal transmission - has two differential amplifiers and includes a current mirror circuit
Inventor: FEINDT HANS-HEINRICH
IPC: H03G1/00
Filed: 1975-06-12
Abstract: The a.c. signal is applied to differential amplifiers as difference signal to conjoined emitter of the first and second, and also of the third and fourth transistors. Bias voltage is applied between joined together control electrodes of the first and fourth, and of the second and third transistor, while the output signal is collected from collectors of the second and third transistors. The third transistor (3) collector controls a current mirror circuit (9-13) which determines direct current flowing from the source (+Ub) to the second transistor (2) collector, so that it is at least approx. equal to the collector direct current. The output terminal (A, 8) connected to the second transistor (2) collector does, therefore, carry no d.c. current.
Patent DE-2532850-A1 (DE)
Inventor: SCHUELLER KARL-HEINZ
IPC: F24D11/02
Filed: 1975-07-23
Abstract: In the method, a heat transfer medium is heated in a heating station (20) and conveyed by pipes (21) to the consumers (11). In order, in such a long-distance heat supply, to be able to increase the output without extending the pipe network (19, 21), which connects the heating station (20) to the consumers (11), the heat transfer medium, which is cooled in the consumers, is divided up into two partial flows and conveyed to a heat pump (26) arranged close to the consumers. Here, one partial flow (10) is further cooled and the heat obtained is used to heat the other partial flow (7) which is then supplied to consumers. In this manner, the heat output available to the consumers is increased without additional loading or extension of the pipe installation, with which the consumers are connected to the heating station. <IMAGE>

Title: Indirectly coupled press. gauge for pipelines - has strain gauge clamped to pipe exterior to measure internal press.
Inventor: GAUCHEL MANFRED
IPC: G01L9/00
Filed: 1975-07-24
Abstract: The pressure transducer for measuring fluid pressure in pipelines consists of a pair of Vee blocks (1) clamped to the outer case of the tube through which the medium is flowing. The blocks form part of a strain gauge measuring apparatus using electrical, pneumatic, hydraulic or mechanical transmission to operate a calibrated indicator unit (3, 4). Changes in pressure within the pipe are sensed as stresses in the tube walls. The pressure gauge requires no direct connection with the fluid medium in the tube and thus prevents inadvertent admission of air, loss of medium or contamination which could possibly occur with manometer-type instruments.

Title: Photographic developer processing tank wiper lips - are profiled for clean operation and to negotiate film joins
Inventor: LEUCHTER JUERGEN
IPC: G03D15/02
Filed: 1975-10-10
Abstract: The usual kind of lips are wedge-shaped, and very thin where they contact the film. To prevent their being too easily deformed by the passing film, their tips are often made of firmer material: but then they tend to jam the film at the double-thickness sections where lengths are joined together. The modified wedge proposed by the invention does not narrow all the way to a thin edge, but terminates in a short section of constant thickness (5); this section can flex at its junction with the wedge (8), while still presenting a firm edge to the film. Behind the wedge, the material narrows to a waist (7), where again flexing is possible, but now only when a double-thickness section passes. Thus jams are eliminated without prejudicing efficient wiping action.
